#1918 UTF-16LE is not supported on libmtp-1.1.17 version.

[FengChen]

It seems that libmtp 1.1.16 supports UTF-16LE, but 1.1.17 is still wrong?
glibc use 2.31 version.

This is probably not a libmtp bug.

Do you have a libmtp installation on this system where this works?

this might mean there are some iconv specific data files missing from the system.

[FengChen]

yes， I installed libmtp-1.1.17，
iconv should be in glibc, I am using glibc version 2.31(/lib64/libc-2.31.so).

What libraries should I install to support it?

Thanks!

Hi Marcus

any update ?

Thanks

Hi Feng,
I have the same issue, I tried with downgrade to libmtp-1.1.16 but still the error.
I think that is a dependency problem.
Could you resolve It?

[Marcus Meissner]

on my system the converters are in

/usr/lib64/gconv/UTF-16.so
/usr/lib64/gconv/UNICODE.so

can you check if you find UTF-16.so and UNICODE.so somewhere on your system?

(It is in the glibc-locale-base package here on opeNSUSE, but its probably called different for your system)
